2.2.1.1 Storm water drains:Conservation of water resource is most important aspect of the project duringconstruction and occupation phases. Storm water drainage planning, domestic waterplanning and sewerage transfer and sewage treatment planning are most essential.The percolation pit is presented in fig 2.4.

Storm water sumps will be provided to meet the expected increase in the runoff duringrainy seasons due to the impervious nature of the Roof, roads and other paved areas.Storm water drainage system shall be provided to collect both the roof water andsurface water generated within the project site. All roof water from terraces of allblocks shall be collected by means of rainwater down take pipes. All roof water downtakes shall be taken up to the ground level and connected to the storm water sumpsfor all blocks excess storm water from terrace will be sent to rainwater harvestingstructures. The storm water coming from roads are connected to water quality inletsand then it is allowed to flow into rain water harvesting structures of size 1.5m X 1.5m X2 m provided at distance of 50 m and excess storm water will be let in to the stormwater drains. Intensity of rainfall of 40 mm/hr shall be considered for design purpose ofstorm water Sumps

2.2.1.2 Water Availability:Water is required for the construction as well as during occupation stage as the same isan important resource. The water requirement during construction is in the order of50 cum/day with a peak demand of 100 cum/day, and during occupation stage in theorder of 169.1 KLD. The water resource available with the Municipal authorities wasstudied to identify the source and feasibility. The water resource both domestic waterand sewage is dealt by the Hyderabad Metropolitan water supply and Sewerage Board(HMWSSB) in the GHMC area. The HMWSSB has been maintaining the water supplyresources for Hyderabad along with the treatment of wastewater. The resourcesavailable with the HMWSSB are presented in table 2.4.

It may be noted that the following water supply projects i.e., Krishna Phase III (Part II)with 45 MGD capacity and Godavari phase – I with 172 MGD capacity is anticipated tobe operational during 2015 and 2016 respectively. It may also be noted that thedependability of Osman sagar and Himiyath sagar is reduced to approximately 60%. 45MGD supply is available.

Domestic Water: It is proposed to draw domestic water from the HyderabadMetropolitan Water Supply and Sewerage Board (HMWSSB) to mitigate the drinkingwater demand, which has been encouraging bulk consumers. The water shortage if anyduring summer season will be drawn from ground water sources. During theconstruction stage, water will be sourced primarily through tankers that would bearranged by the contractor or bulk supplies from HMWS&SB. During the projectoperational stage the water demand shall be sourced bulk supplies from HMWS&SB.The water requirement of the project during occupation stage is in the order of 169.1KLD.

The water requirement for the project during the occupation stage is presented in table2.5. The water savings for the project is presented in table 2.6.

SEWAGE TREATMENT PLANTIt is proposed to provide a sewage treatment plant with a capacity of 170 KLD. The unitoperations of the treatment system are presented below:



Sewage treatment plant based on Fluidized Aerobic Bio Reactor (FAB) technologyPROCESS DESCRIPTION:The raw sewage will be collected in a collection sump and pumped to mechanical barscreen chamber for removal of large floating matter followed by grit removal in GritChamber. The raw sewage will then be collected in an equalization tank forhomogenization of hydraulic load. The tank contents will be kept in suspension bymeans of course bubble serration through pipe grid. The equalization tank, with airflow indicator for continuous monitoring of air supply to the tank in order to avoidseptic conditions, will be covered from top (RCC or FRP) to avoid nuisance. Theequalized effluent will then be pumped to two Fluidized Aerobic Bio Reactors (FAB) inseries where BOD/COD reduction can be achieved by virtue of aerobic microbialactivities. The oxygen required will be supplied through coarse air bubble diffusers.The bio-solids formed in the biological process will be separated in the down streamTube Settler. The clear supernatant will gravitate to the chlorine contact tank wheresodium hypochlorite will be dosed for disinfection of treated water prior to disposal.

The biological sludge generated in the FAB and settled in the tube settlers will becollected in a sludge sump and then pumped to sludge drying bed for de watering. Thedried sludge will then be disposed off suitably as manure. The schematics of theprocess are shown. The two main components of the treatment system viz. The FABreactor and tube settler are described in the following sections.

Fluidized Aerobic Bio Reactor (FAB)Conventional effluent treatment plants are large sized, power intensive and require alot of monitoring. Scarcity of open space and rising land a power costs have forced theindustries to look our for space saving, compact and efficient treatment options. Thishas led to the development attached growth processes where the bio mass is retainedwithin the aeration tank obviating the need for recycle. These plants are not onlycompact but also user friendly. The endeavor to have a continuously operating, no-clogging biofilm reactor with no need for back washing, low head-loss and high specificbiofilm surface area culminated in the most advanced technology of aerobic biologicalfluidized bed treatment where the biofilm (biomass) grows on small carrier elementsthat move along with the water in the reactor. The movement is normally caused byaeration in the aerobic version of the reactor.

The reactor combines all the advantages and best features of Trickling filters, Rotatingbiological contractors, activated sludge process and submerged fixed film reactorswhile eliminating the drawbacks of these systems. The plants are more compact andmore energy efficient.

The Fluidized Aerobic Bio Reactor (FAB) consists of a tank in any shape filled up withsmall carrier elements. The elements are made up of special grade PVC orpolypropylene of controlled density (shown in plate). For media of specific gravity 0.92-0.96 the overall density could be expected to increase up to 9.5% when full of biomasssuch that they can fluidize using an aeration device. A biofilm develops on theelements, which move along the effluent in the reactor. The movement within thereactor is generated by providing aeration with the help of diffusers placed at the



bottom of the reactor. Then thin biofilm on the elements enables the bacteria to actupon the biodegradable matter in the effluent and reduce the BOD/COD content in thepresence of oxygen available from the air that is used for fluidization.

5.0 ENVIRONMENT MANAGEMENT PLAN

M/s. Anantha Infra proposes to construct a Residential project at Vampuguda Kapra,Keesara Mandal, Ranga Reddy District. The area around the village has a number ofresidential development. The project is envisaged as a residential with environmentfriendly features to cater to the growing market demand for quality housing. Thedemand for quality housing from this area will be partially met from this project, apartfrom the demand due to industrial nature of the surrounding areas. The village has anumber of layouts and rapidly turning into a residential zone for various types of socioeconomic sectors.

5.1 PROJECT DETAILSThe project will be spread over an area of 2.0234 hectares of land for residentialpurpose with necessary amenities in Survey nos. 636 Part, Vampuguda Kapra, Keesara,Ranga Reddy District. The project site is surrounded by open lands in all directions. An12 m wide road in North direction connecting High Tension road. The nearest railwaystation is Ammuguda railway station at a distance of 3.5 km.

It is proposed to provide 3 Blocks. Block (A & C) with 2C+G+7 floors, Block B with C+S+5and Amenities block with G+4. It is proposed to provide stilt & 2 cellar floor for parking.The land allocation will be optimized to ensure compliance with the regulations ofGHMC. The water requirement of the project during operation will be drawn fromHMWSSB. Sewage treatment plant will be provided to treat the sewage/wastewater.Water conservation measures will be incorporated in the plumbing designs. Waterrecycling/reuse will be adopted by way of using treated sewage for green beltdevelopment and for flushing. The rainwater will be let-out into the storm water drainand discharged into side drains of road. The required power will be drawn from theTRANSCO and providing open space between each house to allow sunlight will optimizethe energy requirement. Solar Energy will be used for fencing. The designs of thehouses will also incorporate Indian Architectural principles of “Vastu”, as the marketdemands the same. Construction material will be drawn from local sources. Theparking provision follows the guidelines prescribed by GHMC and Building policy.

5.2 MAJOR FINDINGS OF THE EISAn EIA was conducted and the major findings of the EIS study are presented below;

5.3 ENVIRONMENTAL IMPACTSImpact on Physical ResourcesConstruction of proposed project requires huge quantities of natural resources likesand, sub grade and aggregate, and materials produced from natural resources likebricks, cement and steel. The material shall be drawn from local sources, and the leaddistances range from 5 – 150 km. The impacts on physical resources of sand will beirreversible. While bricks will be brought from kilns which use Coal ash. The materialrequirement of steel, cement etc. will be purchased from manufacturers with in state.Hence, no major impacts on physical resources as regards the availability andprocurement of construction material are anticipated due to the project.



Impacts on Air QualityImpacts on air quality during construction stage are likely to be due to operation ofconstruction yards, material transport on trucks and fugitive emissions from theconstruction sites. The model results for occupation stage show slight increase in the airquality and in worst concentrations are falling within the site, and the results are with inthe prescribed limits.

Impacts on Noise QualityImpacts on noise quality during construction stage will be significant. Hence theconstruction near the habitation is proposed only during daytime. The impacts duringoccupation stage will be on the plots adjacent to the road. Construction workers will beprovided with protection equipment to guard against the noise impacts. Noisemitigating measures will be suggested for construction equipment and DG sets.

Impact on FloraThe project site and its surroundings do not form a habitat to any endangered flora.There are very few trees within the project site due to anthropogenic pressures. Theproject will enhance the aesthetics of the site due to the provision of avenue plantationand central greening. This would ensure minimum impact on flora.

Impact on FaunaAs there are no endangered species of wild life in and around the project site, it is likelyto have minimal impact. The avifauna will find abode on the trees proposed to beplanted. This would enhance the aesthetics of the area. Pet animal faeces may leadto pollution of water shed if allowed to join storm water drains.

Impact on Land useThere is no land acquisition for this project. The land use of the site fallow land andclassified as residential by GHMC. However the topography of the land being rockyplains involves cut and fill operations. Erosion and sedimentation are impactsanticipated during construction. Mitigation measures shall be adopted to avoid thesame. The area development would increase the housing activity in the surroundings,which is a positive impact, as barren lands will be used for productive usage, and thenegative impacts will be pressure on the infrastructure facilities.

Impact on Surface Water ResourcesThe degradation of water quality can occur during construction phase from increasedsediment load into watercourses near the construction site. Suitable mitigationmeasures proposed, as part of the EMP will ensure that the residual impacts areminimal. Storm water runoff would increase due to the increase in impervious surface,and rainwater-harvesting structures will be provided as mitigation measure. The designof the storm water drain will consider the additional runoff. The urban storm waterjoining the storm water drain may carry pollutants from imperious surface.



Impact on Ground Water ResourcesGround water shall be drawn during construction, and will be used to augment themunicipal supply during non-monsoon season if necessary. Exploitation of groundwater will have an impact and the same shall be restricted to ensure resourceconservation. This impact will be marginal, as the ground water will not be drawncontinuously.

Impact on Human Use ValuesThe dominant land use in the area is residential, and expected commercial space willincrease the pressure on the residential localities. There is no additional requirementand or acquisition of land. The project authorities will provide road safety measures toreduce risk of accidents in the internal roads. The impact on Human use values ismarginal.

5.4 ENVIRONMENTAL MANAGEMENT MEASURES PROPOSEDA description of the various management measures during the various stages of theproject is provided in the following sections.

5.4.1 Pre-construction stageDuring the design and preconstruction stage the management proposes to comply withthe regulations of town planning, explore the availability of sufficient resources, provideplantation and sink bore wells after obtaining the necessary permissions, obtain allnecessary permissions from various statutory authorities after obtaining the relevantpermissions.

5.4.2 Construction stageThis will be the most crucial and active stage for the Environment Management Plan. Inaddition to the monitoring of the construction activity itself to the pollution levelswithin permissible limits, mitigation and enhancement measures for water resourceswill go on simultaneously as the construction progresses. To facilitate implementationof the enhancement and mitigation measures suggested, working drawings of the samewould be prepared after completion of detailed project report. In addition, the needfor a balanced evaluation and planning for risks associated with construction activitiesrelated to housing project will be part of the supervising Contractors responsibility. Theresource conservation by way of identification of materials and construction debrisrecycle/disposal will be formulated by the supervising consultants. The responsibility ofenvironment management plan lies with the project authorities who would implementthe plan in consultation with other consultants, by including appropriate provisions inthe contract/sub contract documents and providing the necessary facilities.

5.4.3 Operation stageThe environment management plan will be implemented by ownersassociations/societies, where project authorities are co opted as members, and whilethe management plan related to the utilities like roads, street lighting and commonopen spaces lies with the Municipality. The management in operation stage willessentially entail maintenance of sewage treatment plant, maintenance of utilities, andmonitoring activity in the project site. Monitoring for pollutants specified in theMonitoring Plan will serve the two purposes. In addition to checking the efficiency of



the protection/mitigation/enhancement measures implemented, this will help verify orrefute the predictions made as a part of the impact assessment. Thus, it will complete avery important feedback loop for the housing project.

The measures adopted and/or to be adopted during different stages of the project havebeen detailed in table 5.1.

5.5 IMPLEMENTATION ARRANGEMENTSThe responsibility of implementing the mitigation measures lies with project authorityduring design and construction stages while the responsibility lies with the M/s.Anantha Infra Management and Municipality during occupation stage. All constructionactivities taken up by the project authorities will be supervised by the SupervisionConsultant (SC). Implementation schedule will be worked for phase wiseimplementation of the mitigation measures after completion of detailed designs. In thepre-construction phase of the project the supervision consultants shall review the EMPto identify environmental and social issues and arrive at a suitable strategy forimplementation. The activities to be carried out and the target dates will be worked outafter completion of detailed designs.

5.6 INSTITUTIONAL STRENGTHENINGThe management of M/s. Anantha Infra will evaluate the organizational structure withrespect to inadequacies in implementing the environment management plans. Thehousing project is typical as the responsibility of management lies with theowners/residents during occupation stage. The owners form a cooperativesociety/association to manage the utilities and common areas in a normal case. Thecommon areas, electrical supply, street lighting, open space of central green will betaken over and managed by the local body and TRANSCO. The role of residents islimited to being stakeholders with little say in the day-to-day matters; this issue mustbe addressed by the town planning agencies and the government.

The Environment Management Plan envisages on-site monitoring of constructionactivities for environmental pollution and will involve collection of samples and theirsubsequent analysis. For this purpose two chemists would be required especially whenthe implementation of the two phases goes on simultaneously. Induction of two moreassistant engineers, one each for the biophysical and social environment will also benecessary.

5.7 TRAININGThe existing supervising staff and the additional staff have to be trained to effectivelycarry out.

Co-ordinate, with supervision consultants and contractors on compliancemonitoring of mitigation measures during construction phase.

Monitoring of environmental components in the operation stage; Co-ordinate with concerned departments on environmental issues; Environmental impact studies for future housing projects; Liase with State and Government of India on fiscal policies to reduce

environmental pollution from housing activity.

5.8 ENVIRONMENTAL MONITORING5.8.1 IntroductionThe environmental monitoring programme provides such information on whichmanagement decision may be taken during construction and occupation phases. Itprovides basis for evaluating the efficiency of mitigation and enhancement measuresand suggest further actions that need to be taken to achieve the desired effect.



The monitoring includes:(i) Visual observations;(ii) Selection of environmental parameters at specific locations;(iii) Sampling and regular testing of these parameters.

5.8.2 ObjectivesThe objectives of the environmental monitoring programme are:

Evaluation of the efficiency of mitigation and enhancement measures; Updating of the actions and impacts of baseline data; Adoption of additional mitigation measures if the present measures are

insufficient; Generating the data, which may be incorporated in environmental

management plan in future projects.

5.8.3 MethodologyMonitoring methodology covers the following key aspects:

Components to be monitored; Parameters for monitoring of the above components; Monitoring frequency; Monitoring standards; Responsibilities for monitoring; Direct responsibility, Overall responsibility; Monitoring costs.

Environmental monitoring of the parameters involved and the threshold limits specifiedare discussed below.

5.8.4 Ambient Air Quality (AAQ) MonitoringAmbient air quality parameters recommended for road transportation developmentsare Respirable Particulate Matter (RPM), Suspended Particulate Matter (SPM), Oxidesof Nitrogen (NOX), Sulphur Dioxide (SO2) and Lead (Pb). These are to be monitored atdesignated locations starting from the commencement of construction activity. Datashould be generated over three days at all identified locations in accordance to theNational Ambient Air Quality Standards (Table 5.2) location, duration and the pollutionparameters to be monitored and the responsible institutional arrangements aredetailed out in the Environmental Monitoring Plan.

5.9 REPORTING SYSTEMReporting system provides the necessary feedback for project management to ensurequality of the works and that the program is on schedule. The rationale for a reportingsystem is based on accountability to ensure that the measures proposed as part of theEnvironment Management Plan get implemented in the project.

The reporting system will operate linearly with the contractor who is at the lowest rungof the implementation system reporting to the Supervision Consultant, who in turn shallreport to the M/s. Anantha Infra. All reporting by the contractor and SupervisionConsultant shall be on a quarterly basis. M/s. Anantha Infra shall be responsible forpreparing targets for each of the identified EMAP activities. All subsequent reporting bythe contractor shall be monitored as per these targets set by the M/s. Anantha Infra,before the contractors move on to the site. The reporting by the Contractor will be amonthly report like report of progress on construction and will form the basis formonitoring by the M/s. Anantha Infra either by its own Environmental Cell or theEnvironmental Specialist hired by the Supervision Consultant.

Monitoring of facilities at construction camps Monitoring of air, noise, soil and water parameters including silt load Monitoring of survival rate of plantation. Monitoring of cleaning of drains and water bodies.

5.10 ENVIRONMENTAL MANAGEMENT BUDGETThe environmental budget for the various environment management measuresproposed in the EMP is detailed in Table 5.6 There are several other environmentalissues that have been addressed as part of good engineering practices, the costs for



which has been accounted for in the Engineering Costs. Moreover, since environmentalenhancements have not been finalized at this stage, the table projects the typical costsaspect wise and the detailed cost estimate is presented in Annexure A.

5.11 Horticultural and Landscaping Works(a) ScopeThe Horticultural and Landscaping works may be entrusted to a contractor. It wouldgenerate local employment if the plantation, upkeep and maintenance of the green beltwere entrusted to local VSS bodies. Detailed drawings and designs of landscaping willbe drawn after completion of the detailed designing. The following precautions mustbe taken while undertaking horticulture and landscaping works. The M/s. Anantha Infraproject will have greenery by way of avenue plantation and central green. The schemeof plantation and the figures are presented in mitigation chapter. The upkeep and themanagement of the greening are presented as follows:

b) MaterialsPlant MaterialsPlant Materials shall be well formed and shaped true to type, and free from disease,insects and defects such as knots, sun-scaled, windburn, injuries, abrasion ordisfigurement.



All plant materials shall be healthy, sound, vigorous, free from plant diseases, insectspests, of their eggs, and shall have healthy, well-developed root systems. All plants shallbe hardy under climatic conditions similar to those in the locally of the project. Plantssupplied shall to confirm to the names listed on both the plan and the plant list. Noplant material will be accepted if branches are damaged or broken. All material must beprotected from the sun and weather until planted.

Any nursery stock shall have been inspected and approved by the EnvironmentalSpecialist or the Engineer. All plants shall conform to the requirements specified in theplant list. Except that plants larger then specified may be used if approved, but use ofsuch plants shall not increase the contract price. If the use of the larger plant isapproved, the spread of roots or ball of earth shall be increased in proportion to thesize of plant. Deliver plants with legible identification labels.

Top Soil (Good Earth)Topsoil or good earth shall be a friable loam, typical of cultivated top soils of the localitycontaining at least 2% of decayed organic matter (humus). It shall be taken from a well-drained arable site. It shall be free of subsoil, stones, earth skids, sticks, roots or anyother objectionable extraneous matter or debris. It shall contain no toxic material. Notopsoil shall be delivered in a muddy condition. It shall have pH value ranging between6 and 8.5.

FertiliserMeasurement of sludge shall be in stacks, with 8% reduction for payment. It shall befree from extraneous matter, harmful bacteria insects or chemicals. (Subjected tosafety norms).

Root SystemThe root system shall be conducive to successful transplantation. While necessary, theroot-ball shall be preserved by support with Hessian or other suitable material. On soilswhere retention of a good ball is not possible, the roots should be suitably protected insuch a way that the roots are not damaged.

ConditionTrees and shrubs shall be substantially free from pests and diseases, and shall bematerially undamaged. Torn or lacerated roots shall be pruned before dispatch. Noroots shall be subjected to adverse conditions such as prolonged exposure to dryingwinds or subjection to water logging between lifting and delivery.

(c) Supply and SubstitutionUpon submission of evidence that certain materials including plant materials are notavailable at time of contract, the contractor shall be permitted to substitute with anequitable adjustment of price. All substitutions shall be of the nearest equivalentspecies and variety to the original specified and shall be subjected to the approval ofthe Landscape Architect.



(d) PackagingPackaging shall be adequate for the protection of the plants and such as to avoidheating or drying out.

(e) MarkingEach specimen of tree and shrub, or each bundle, shall be legibly labelled with thefollowing particulars:

Its name. The name of the supplier, unless otherwise agreed. The date of dispatch from the nursery.

(f) Tree PlantingPlants and ShrubsTrees should be supplied with adequate protection as approved. After delivery, ifplanting is not to be carried out immediately, balled plants should be placed back toback and the ball covered with sand to prevent drying out. Bare rooted plants can beheeled in by placing the roots in prepared trench and covering them with earth, whichshould be watered into, avoid air pockets round the roots. Trees and shrubs shall beplanted as shown in architectural drawings and with approval of site supervisionengineer.

Digging of PitsTree pits shall be dug a minimum of three weeks prior to backfilling. The pits shall be120 cm in diameter and 120 cm deep. While digging the pits, the topsoil up to a depthof 30 cm may be kept aside, if found good (depending upon site conditions), and mixedwith the rest of the soil.

If the side of the below, it shall be replaced with the soil mixture as specified furtherherein. If the soil is normal it shall be mixed with manure; river sand shall be added tothe soil if it is heavy. The bottom of the pit shall be forked to break up the subsoil.

Back FillingThe soil back filled watered through and gently pressed down, a day previous toplanting, to make sure that it may not further settle down after planting. The soil shallbe pressed down firmly by treading it down, leaving a shallow depression all round forwatering.

PlantingNo tree pits shall be dug until final tree position has been pegged out for approval. Careshall be taken that the plant sapling when planted is not be buried deeper than in thenursery, or in the pot. Planting should not be carried out in waterlogged soil. Planttrees at the original soil depth; soil marks on the stem is an indication of this and shouldbe maintained on the finished level, allowing for setting of the soil after planting. Allplastic and other imperishable containers should be removed before planting. Anybroken or damage roots should be cut back to sound growth.

The bottom of the planting pit should be covered with 50mm to 75mm of soil. Bareroots should be spread evenly in the planting pit; and small mound in the centre of the



pits on which the roots are placed will aid on even spread. Soil should be placed aroundthe roots, gently shaking the tree to allow the soil particles to shift into the root systemto ensure close contact with all roots and prevent air pockets. Back fill soil should befirmed as filling proceeds, layer by layer, care being taken to avoid damaging the roots,as follows:

The balance earth shall be filled in a mixture of 1:3 (1 part sludge to 3 part earth byvolume) with 50 gm potash, (Mop) 50gms of Super Phosphate and 1Kg. Neem oil cake.Aldrin or equivalent shall be applied every 15 days in a mixture of 5ml in 5 litres ofwater.

StakingNewly planted trees must be held firmly although not rigidly by staking to prevent apocket forming around the stem and newly formed fibrous roots being broken bymechanical pulling as the tree rocks.

Methods:The main methods of staking shall be:

(a) A single vertical shake, 900mm longer than the clear stem of the tree, driven600mm to 900mm into the soil.

(b) Two stakes as above driven firmly on either side of the tree with a cross bar towhich the stem is attached. Suitable for bare- rooted or Ball material.

(c) A single stake driven in at an angle at 45 degrees and leaning towards theprevailing wind, the stem just below the lowest branch being attached to thestake. Suitable for small bare- rooted or Ball material

(d) For plant material 3m to 4.5m high with a single stem a three- wire adjustable guysystem may be used in exposed situations.

The end of stake should be pointed and the lower 1m to 1.2m should be coated with anon-injurious wood preservative allowing at least 150mm above ground level.

TyingEach tree should be firmly secured to the stake so as to prevent excessive movement.Abrasion must be avoided by using a buffer, rubber or Hessian, between the tree andstake. The tree should be secured at a point just below its lowest branch, and also justabove ground level; normally two ties should be used for tree. These should beadjusted or replaced to allow for growth.

WateringThe Landscape Contractor should allow for the adequate watering in of all newlyplanted trees and shrubs immediately after planting and he shall during the followinggrowing season, keep the plant material well watered.

FertilisingFertilising shall be carried out by application in rotation of the following fertilisers, every15 days from the beginning of the monsoon till the end of winter:

(1) Sludge or organic well-rotted dry farm yard manure: 0.05 cum or tussle.



(2) Urea 25 gm.(3) Ammonium sulphate 25 gm.(4) Potassium sulphate 25 gm.

All shrubs, which are supplied pot grown, shall be well soaked prior to planting.Watering in and subsequent frequent watering of summer planted container- grownplants is essential.

(g) Shrub Planting In Planter BedsAll areas to be planted with shrubs shall be excavated, trenched to a depth of 750 mm,refilling the excavated earth after breaking clods and mixing with sludge in ratio 8:1 (8parts of stacked volume of earth after reduction by 20%: 1 part of stacked volume ofsludge after reduction by 8%.)

Tall shrubs may need staking, which shall be provided if approved by the contractingconsulting engineer, depending upon the conditions of individual plant specimen. Forplanting shrubs and ground cover shrubs in planters, good earth shall be mixed withsludge in the proportion as above and filled in planters.

Positions of planters shall be planted should be marked out in accordance with thearchitectural drawing. When shrubs are set out, precautions should be taken to preventroots drying. Planting holes 40 cm in diameter, and 40 cm deep should be excavated forlonger shrubs. Polythene and other non-perishable containers should be removed andany badly damaged roots carefully pruned. The shrubs should then be set in holes sothat the soil level, after settlement, will be original soil mark on the stem of the shrub.The holes should be back filled to half of its depth and firmed by treading. Theremainder of the soil can then be returned and again firmed by treading.

(h) GrassingPreparationDuring period prior to planting the ground shall be maintained free from weeds.Grading and final weeding of the area shall be completed at least three weeks prior tothe actual sowing. Regular watering shall be continued until sowing by dividing the areainto portions of approximately 5m squares by constructing small bunds to retain water.These 'bunds' shall be levelled just prior to sowing of grass plants; it shall be ensuredthat the soil has completely settled.

SoilThe soil itself shall be ensured to the satisfaction of Landscape Architect to be a goodfibrous loam, rich in humus.

Sowing the grass rootsGrass roots (cynodon, dectylon or a local genus approved by the Landscape Architect)shall be obtained from a grass patch, seen and approved before hand.

The grass roots stock received at site shall be manually cleared of all weeds and watersprayed over the same after keeping the stock in place protected from sun and drywinds.



Grass stock received at site may be stored for a maximum of three days. In casegrassing for some areas is scheduled for a later date fresh stock of grass roots shall beordered and obtained.

ExecutionSmall roots shall be dibbled about 5 cm apart into the prepared grounds. Grass willonly be accepted as reaching practical completion when germination has provedsatisfactory and all weeds have been removed.

MaintenanceAs soon as the grass is approximately a 3cm high it shall be rolled with a light woodenroller – in fine, dry weather – and when it has grown to 5 to 8 cm, above to groundweeds must be removed and regular cutting with the scythe and rolling must be begun.A top-dressing of an ounce of guano to the square yard or well decomposed wellbroken sludge manure shall be applied when the grass is sufficiently secure in theground to bear the mowing machine, the blades must be raised an inch above thenormal level for the first two or three cuttings. That is to say, the grass should be cut sothat it is from 4 to 5 cm in length, instead of the 3 cm necessary for mature grass.

In the absence of rain, in the monsoon, the lawn shall be watered every ten daysheavily, soaking the soil through to a depth of at least 20 cm.

Damage failure or dying back of grass due to neglect of watering especially for seedingout of normal season shall be the responsibility of the contractor. Any shrinkage belowthe specified levels during the contract or defect liability period shall be rectified at thecontractor's expense. The Contractor is to exercise care in the use of rotary cultivatorand mowing machines to reduce to a minimum the hazards of flying stones andbrickbats. All rotary mowing machines are to be fitted with safety guards.

RollingA light roller shall be used periodically, taking care that the area is not too wet andsodden.

EdgingThese shall be kept neat and must be cut regularly with the edging shears.

FertilisingThe area shall be fed once in a month with liquid manure prepared by dissolving 45gmsof ammonium sulphate in 5 litres of water.

WateringWater shall be applied at least once in three days during dry weather. Wateringwhenever done should be thorough and should wet the soil at least up to a depth of20 cm.

WeedingPrior to regular mowing the contractor shall carefully remove rank and unsightly weeds.



CultivatingThe Landscape Contractor shall maintain all planted areas within Landscape contractboundaries for one year until the area is handed over in whole or in phases.Maintenance shall include replacement of dead plants, watering, weeding, cultivating,control of insects, fungus and other diseases by means of spraying with an approvedinsecticide or fungicide, pruning, and other horticulture operations necessary for propergrowth of the plants and for keeping the landscape sub-contract area neat inappearance.

Pruning and RepairsUpon completion of planting work of the landscape sub-contract all trees should bepruned and all injuries repaired where necessary. The amount of pruning shall belimited to the necessary to remove dead or injured twigs and branches and tocompensate for the loss of roots and the result of the transplanting operations. Pruningshall be done in such a manner as not to change the natural habit or special shape oftrees.

Tree GuardsWhere the tree guards are necessary, care should be taken to ensure that they do notimpede natural movement or restrict growth. Circular iron tree guards shall be providedfor the trees at enhancement locations. The specifications for which one given below:

Circular Iron Tree Guard with Bars.The tree guard shall be 50 cm. in diameter.

The tree guards shall be formed of (i) 5 Nos. 25x25x3mm angle iron verticals 2.00m longexcluding splayed outward at lower end up to an extent of 10 cms.

(i) Nursery StackPlanting should be carried out as soon as possible after reaching the site. Whereplanting must be a necessity and/or be delayed, care should be taken to protect theplants from pilfering or damage from people animals. Plants with bare-roots should beheeled- in as soon as received or otherwise protected from drying out, and others setclosely together and protected from the wind. If planting is to be delayed for more thana week, packaged plants should be unpacked, the bundles opened up and each group of



plants heeled in separately and clearly labelled. If for any reason the surface of theroots becomes dry the roots should be thoroughly soaked before planting.

(j) Protective FencingAccording to local environment, shrubs shall be protected adequately from vandalismuntil established.

(k) CompletionOn completion, the ground shall be formed over and left tidy.

5.12 Water Conservation MeasuresWater conservation measures must be adopted during the occupation stage that wouldconserve the natural resource and also reduce the pressure on other users. Typical listsof water conservation measures are presented as follows;

Household Water Saving Measures1. There are a number of ways to save water and they all start with you.2. When washing dishes by hand, don't let the water run while rinsing. Fill one sink withwash water and the other with rinse water.3. Check your sprinkler system frequently and adjust sprinklers so only your lawn iswatered and not the house, sidewalk, or street.4. Run your washing machine and dishwasher only when they are full and you couldsave 3785 liters a month.5. Avoid planting turf in areas that are hard to water such as steep inclines and isolatedstrips along sidewalks and driveways.6. Install covers on pools and check for leaks around your pumps.7. Use the garbage disposal less often.8. Plant during rainy season and or winter when the watering requirements are lower.9. Check your water meter and bill to track your water usage.10. Always water during the early morning hours, when temperatures are cooler, tominimize evaporation.11. Wash your produce in the sink or a pan that is partially filled with water instead ofrunning water from the tap.12. Use a layer of organic mulch around plants to reduce evaporation and savehundreds of liters of water a year.13. Use a broom instead of a hose to clean your driveway and sidewalk and save up to303 liters of water every time.14. If your shower can fill 4 liters bucket in less than 20 seconds, and then replace itwith a water-efficient showerhead.15. Collect the water you use for rinsing produce and reuse it to water houseplants.16. Water your lawn in several short sessions rather than one long one. This will allowthe water to be better absorbed.17. We’re more likely to notice leaky faucets indoors, but don’t forget to check outdoorfaucets, pipes, and hoses for leaks.18. Only water your lawn when needed. You can tell this by simply walking across yourlawn. If you leave footprints, it’s time to water.19. When you shop for a new appliance, keep in mind that one offering severaldifferent cycles will be more water and energy-efficient.



20. Time your shower to keep it under 5 minutes. You’ll save up to 3785 liters a month.21. Install low-volume toilets.22. When you clean your fish tank, use the water you’ve drained on your plants. Thewater is rich in nitrogen and phosphorus, providing you with a free and effectivefertilizer.23. Water small areas of grass by hand to avoid waste.24. Put food coloring in your toilet tank. If it seeps into the toilet bowl, you have a leak.It's easy to fix, and you can save more than 2271 liters a month.25. Plug the bathtub before turning the water on, then adjust the temperature as thetub fills up.26. Use porous materials for walkways and patios to keep water in your yard andprevent wasteful runoff.27. Designate one glass for your drinking water each day. This will cut down on thenumber of times you run your dishwasher/wash your utensils.28. Instead of using a hose or a sink to get rid of paints, motor oil, and pesticides,disposes of them properly by recycling or sending them to a hazardous waste site.29. Install a rain shut-off device on your automatic sprinklers to eliminate unnecessarywatering.30. Don’t use running water to thaw food.31. Choose water-efficient drip irrigation for your trees, shrubs, and flowers. Wateringroots is very effective, be careful not to over water.32. Grab a wrench and fix that leaky faucet. It’s simple, inexpensive, and can save 530liters a week.33. Cut back on the amount of grass in your yard by planting shrubs and ground coveror landscaping with rock.34. When doing laundry, match the water level to the size of the load.35. Teach your children to turn the faucets off tightly after each use.36. Remember to check your sprinkler system valves periodically for leaks and keep theheads in good shape.37. Before you lather up, install a low-flow showerhead. They’re inexpensive, easy toinstall, and can save your family more than 1900 liters a week.38. Soak your pots and pans instead of letting the water run while you scrape themclean.39. Don’t water your lawn on windy days. After all, sidewalks and driveways don’t needwater.40. Water deeply but less frequently to create healthier and stronger landscapes.41. Make sure you know where your master water shut-off valve is located. This couldsave liters of water and damage to your home if a pipe were to burst.42. When watering grass on steep slopes, use a soaker hose to prevent wasteful runoff.43. To get the most from your watering time, group your plants according to their waterneeds.44. Remember to weed your lawn and garden regularly. Weeds compete with otherplants for nutrients, light, and water.45. While fertilizers promote plant growth, they also increase water consumption.Apply the minimum amount of fertilizer needed.46. Avoid installing ornamental water features unless the water is being recycled.47. Use a commercial car wash that recycles water.48. Don’t buy recreational water toys that require a constant flow of water.



49. Turn off the water while you brush your teeth and save 15 liters a minute. That’s760 liters a week for a family of four.50. Encourage your school system and local government to help develop and promote awater conservation ethic among children and adults.51. Teach your family how to shut off your automatic watering systems so anyone whois home can turn sprinklers off when a storm is approaching.52. Set a kitchen timer when watering your lawn or garden with a hose.53. Make sure your toilet flapper doesn’t stick open after flushing.54. Make sure there are aerators on all of your faucets.55. Next time you add or replace a flower or shrub, choose a low water use plant foryear-round landscape color and save up to 2085 liters each year.56. Spot spray or remove weeds as they appear.57. Use a screwdriver as a soil probe to test soil moisture. If it goes in easily, don’twater. Proper lawn watering can save thousands of liters of water annually.58. Install a drip irrigation system around your trees and shrubs to water moreefficiently.59. Mow your lawn as infrequently as possible. Mowing puts your lawn underadditional stress, causing it to require more water.60. Don’t use the sprinklers just to cool off or for play. Running through water from ahose or sprinkler wastes gallons of water.61. Make sure your swimming pools, fountains, and ponds are equipped withrecirculating pumps.62. Bathe your young children together.63. Direct downspouts or gutters toward shrubs or trees.64. Insulate hot water pipes so you don’t have to run as much water to get hot water tothe faucet.65. Drop that tissue in the trash instead of flushing it and save liters every time.66. If you have an evaporative air conditioner, direct the water drain to a flowerbed,tree, or your lawn.67. Make suggestions to your employer to save water (and dollars) at work.68. When brushing your teeth never leave tap water running.69. Use a hose nozzle and turn off the water while you wash your car and save morethan 380 liters.

5.13 Energy Efficiency Measures in a Typical Household5.13.1 Hot Water Repair leaky faucets. Reduce the temperature setting of your water heater to warm (500 C). Add an insulating blanket to your water heater. Install low-flow showerheads. Wash clothes in warm or cold water using the appropriate water level settingfor the

load. Replace water heater, when needed, with an energy efficient model.

Major Appliances and Other Appliances Maintain refrigerator at 2 to 50 C and freezer section at –15 0 C. Maintain stand alone freezer at 0 F. Choose a refrigerator/freezer with automatic moisture control.



Use toaster ovens or microwave ovens for cooking small meals. Adjust the flame on gas cooking appliances so it’s blue, not yellow. Replace a gas-cooking appliance with a unit with an automatic, electric ignition

system. Run the dishwasher only with a full load of dishes. Air dry dishes in a dishwasher. Shut down home computers when not in use. Select appliances (i.e., curling irons, coffee pots, irons) with time limited shut off

switches. Replace aging major appliances, TVs and VCRs when needed, with energy

efficient models. Replacing a 1970s refrigerator with an energy efficiencyrefrigerator. This can save over 2,000 kWh per year. This will also reducecarbon dioxide emissions by over 2,000 pounds every year.

Increase Air Conditioner thermostat by 3 degrees F. This can save over 900 kWhper year, annually and over 900 pounds of carbon dioxide each year. Dependingon the size of your home, you can save 3% on your cooling costs for everydegree you raise your thermostat in the summer. Raising the thermostat from73 to 78 F degrees can reduce cooling costs by 15%.

Make sure your air conditioner is the proper size for the area you are cooling.An air conditioner that is too large will use more electricity than needed; an airconditioner that is too small will have to work harder to cool a space. Therecommended Air conditioners based on the room size are as follows:

Area To Be Cooled (sq. ft.) Capacity (BTU/HR)100 to 150 5,000150 to 250 6,000250 to 300 7,000300 to 350 8,000350 to 400 9,000400 to 450 10,000450 to 550 12,000500 to 700 14,000

700 to 1,000 18,000

Only run the washing machine, dryer, and dishwasher when you have full loads.Cool only the rooms you use and utilize fans when the temperature is moderate.

Lighting

Turn off lights when not in use.

Use task lighting whenever possible instead of brightly lighting an entire room.

Install compact fluorescent lamps in the fixtures which receive high use. Replacethe five most frequently used incandescent light bulbs with compact fluorescentbulbs. This will save over 500 kWh per year, and over 500 pounds of CO2.
